I am building a system for a buddy and it is made up of the following:
ASUS M2N-E SLi - Motherboard
AMD Athalon 2600+ - CPU
Corsair TX750w - PSU
eVGA 9500GT 512mb
2x MUSHKIN Redline XP2-8000
3 x Western Digital HDD
Sony DVD-R

Everything seems to be working fine, all of the fans turn on and all the LED's. But No beep....
I read this is most likely a RAM problem, but I have swaped through 6 different sticks in no real order.
Starting to lost my mind here... If it's not beeping and its not RAM???

Did you check the CPU compatibility chart for your motherboard? You have an Am2 motherboard. That Cpu you have isn't compatible. Check here ASUSTeK Computer Inc.
I think what you have will work on a Socket A mobo. And what's with the 750W PSU? It's pretty overkill for that setup.

If it is a 6000+, I seem to recall the early AM2 boards having some issues with 125W CPU's. They were real finicky with ram as well. You might need to find a generic low end stick (5300/5400), get it to boot and crank up the memory voltage.

Another option I would recommend (if the CPU is vaild check the mobo website for cpu compatibility) I'm at work or I would for you.

If thats good to go then only use one stick of ram to get it up and running (install OS etc) also the board will probably be picky on RAM so once up and running do the bios updates right away (make sure you know how to do this or get someone that can). Then make sure you put your ram in the dual
channel mode properly and everything should be fine.

Using one stick of ram sometimes to get things going is a good option I've used it many a time and then once its up and running and I've updated bios, and put the ram in the right order it works fine.
